Go 中啟動其他程式並擷取其輸出

Go還是挺可愛的，蠻喜歡~文法以及內建函數庫都不錯。

 

// execpackage mainimport (    "fmt"    "os/exec")func main() {    cmd := exec.Command("cmd.exe", "/c", "tasklist")    var buf []uint8    var err error    err = nil    if nil == err {        buf, err = cmd.Output()        if err != nil {            fmt.Printf("%t", err)            return        }    } else {        fmt.Printf("fatal error:%t", err)        return    }    var c uint8    line := []uint8{}    jump := false    for i := 0; i < len(buf); i += 1 {        c = buf[i]        if jump == true {            if c == uint8('\n') {                jump = false            }            continue        }        if c > 0x7f {            jump = true            line = []uint8{}            fmt.Println("One line skipped.")            continue        }        if c == uint8('\n') {            fmt.Printf("%s\n", line)            line = []uint8{}            continue        }        line = append(line, c)    }}
